The object expirer can be configured to delay the reaping of
objects from disk after their expiration time using account
and container level delay_reaping values. The delay_reaping
value of accounts and containers in seconds is configured in
the object server config. The object expirer references these
configured values to only reap objects from specified accounts
and containers after their corresponding delays.
The goal of the delay_reaping feature is to prevent accidental or
premature data loss if an object marked for deletion with the
'x-delete-at' feature should not be reaped immediately, for
whatever reason.
Configuring the delay_reaping value at a granular account and
container level is beneficial for being able to keep storage
capacity consumption in control while maintaining a desired
data recovery window.
This patch also adds a sample configuration, documentation, and
tests for bad configurations and grace period functionality.

The last time I really looked at this was probably Yoga, when we were
targetting 3.6 through 3.9 (and left 3.7 and 3.8 as experimental jobs).
Now, though, OpenStack is targetting 3.8 through 3.11; as before, we
can assume that if tests pass on those two versions, they should pass
on the versions in-between, too. (But still have them as experimental,
on-demand jobs).
See https://governance.openstack.org/tc/reference/runtimes/2024.1.html
Keep 2.7 and 3.6 testing as our own self-imposed minimums.

This change allows individual SLO segments to be downloaded by adding
an extra 'part-number' query parameter to the GET request. You can
also retrieve the Content-Length of an individual segment with a HEAD
request.

Currently when the memcachering `_get_conns` method runs out of memcached
servers to try and so fails to yield anything we log a:
 All memcached servers error-limited
However, this error message isn't entirely accurate. It can also fail
because it failed to connect all it's memcached servers not just because
they're error limited.
You can disable error-limiting of memcached servers. So in this case
this error message is a red-herring.
Downstream we use a mcrouter client on each node which itself talks to a
bunch of memcache servers. Therefore in swift's memcachering client we
only configure the 1 mcrouter client as a single server in the ring.
Because of this we disable memcached error-limiting.
If the node gets too overloaded we've had timeouts talking to the local
mcrouter client. This fires off error-limitted log messages which can
confuse things.
Because it's possible to turn off error-limiting, the log line isn't
quite adequate anymore. So this patch changes it to:
 No more memcached servers to try

CentOS 7 will go EOL later this year, and infra wants to drop the nodes
soon-ish -- don't make them wait on our account.
The only major loss is py2 probe tests, but officially, yoga was the
last release we pledged to support py2.

Since we fake out all the greenthread stuff to run in the main thread,
we can (sometimes?) find that a transaction ID has already been set,
leading to failures in test_bad_request_app_logging like
 AssertionError: b'X-Trans-Id: test-trans-id' not found
 in b'X-Trans-Id: tx...'
By resetting the logger's txn_id, we're assured that our mock will be
run and the expected transaction ID will be used.

Currently, when object-server serves GET request and DiskFile
reader iterate over disk file chunks, there is no explicit
eventlet sleep called. When network outpace the slow disk IO,
it's possible one large and slow GET request could cause
eventlet hub not to schedule any other green threads for a
long period of time. To improve this, this patch add a
configurable sleep parameter into DiskFile reader, which
is 'cooperative_period' with a default value of 0 (disabled).

Object GET requests with a truthy X-Newest header are not resumed if a
backend request times out. The GetOrHeadHandler therefore uses the
regular node_timeout when waiting for a backend connection response,
rather than the possibly shorter recoverable_node_timeout. However,
previously while reading data from a backend response the
recoverable_node_timeout would still be used with X-Newest requests.
This patch simplifies GetOrHeadHandler to never use
recoverable_node_timeout when X-Newest is truthy.

Both GetOrHeadHandler (used for replicated policy GETs) and
ECFragGetter (used for EC policy GETs) have _get_next_response_part
methods that are very similar. This patch replaces them with a single
method in the common GetterBase superclass.
Both classes are modified to use *only* the Request instance passed to
their constructors. Previously their entry methods
(GetOrHeadHandler.get_working_response and
ECFragGetter.response_parts_iter) accepted a Request instance as an
arg and the class then variably referred to that or the Request
instance passed to the constructor. Both instances must be the same
and it is therefore safer to only allow the Request to be passed to
the constructor.
The 'newest' keyword arg is dropped from the GetOrHeadHandler
constructor because it is never used.
This refactoring patch makes no intentional behavioral changes, apart
from the text of some error log messages which have been changed to
differentiate replicated object GETs from EC fragment GETs.

We seemed to be relying a little too heavily upon prompt garbage
collection to log client disconnects, leading to failures in
test_base.py::TestGetOrHeadHandler::test_disconnected_logging
